its on the step by step
Step-by-step explanation:
V = π· r2· h
V = π· 10.502· 40
V =13854.4 cm3
Answer:
Step-by-step explanation:
we know that
In the right triangle WVX

Remember that
------> equation A
Because are complementary angles
In the right triangle VXY

substitute the values in the equation A
Rewrite the expression
Area= r*r*π (π ≈ 3.14)
⇒ Area= 4*4* π= 50.265
The area of the circle is 50.265~
Step-by-step explanation:
The total degrees is always 360. So whe get 360=180+3x. 360-180=3x. 180=3x. x=60. I don't know how you're supposed to get 84 degrees.
